  • This randomized pre-post-controlled experimental study determined the effect on patients' anxiety, stress, systolic blood pressure, heart rate and Bis index when the Healing Beats program is applied after epidural blockage. The subjects were selected from the patients who visited the Department of Anesthesiology and Pain for the treatment of epidural blockage and volunteered through the recruitment announcement. A total of 74 sets of data were collected and analyzed with 25 subjects in the experimental group, 24 in the placebo group, and 25 in the control group. The data was analyzed using descriptive statistics, x2-tests, F-tests and repeated measures of ANOVA. As a result of the study, the general characteristics and variables of the experimental group, placebo group, and control group were all the same, and anxiety was measured twice before and after the study. There were significant differences between groups (F=27.175, p<.001), and stress (F=4.78, p<.001), heart rate (F=4.22, p<.001) and the Bis index (F=7.96, p<.001) were analyzed by variance according to population and time. There was a significant difference. However, there was no significant difference in systolic blood pressure (F=1.23, p=.298). In conclusion, the Healing Beats program can be used as an effective and effective intervention for sedation in clinical situations or stressful situations.

  • Purpose: This study investigated the effects of an eye care protocol (ECP) on patients in the intensive care unit (ICU). Methods: This study utilized a randomized controlled design. Participants were patients who met the inclusion criteria and were admitted to the ICU (36 in the experimental group and 38 in the control group). The experimental group received an ECP, while the control group received standard eye care, starting the day after admission, for a duration of 10 days. The ECP classifies the degree of eyelid obstruction into three stages based on the degree of exposure to the lower eyelid conjunctiva and cornea. The protocol included cleansing with normal saline gauze, administering eye drops, applying silicone and polyurethane films, and recommending consultation with an ophthalmologist if necessary. The effectiveness of ECP was assessed by analyzing tear volume, hyperemia, chemosis, and eye discharge. Data analysis was conducted using SPSS 27.0, employing the Mann-Whitney U-test and generalized estimating equations. Results: On day 5, the experimental group demonstrated a significant increase in tear volume in both eyes compared with the control group. However, no statistically significant differences were observed in the incidence of hyperemia, chemosis, and eye discharge on days 5 and 10 of the intervention. Conclusion: The application of the ECP in this study increased tear volume in ICU patients, thereby reducing discomfort caused by dry eyes. It has the potential to prevent complications such as damage to the surface of the eyeball resulting from decreased tear volume.

  • The purpose of this study was to determine whether wrist stabilization exercise combined with taping would improve wrist pain, disability and quality of life in postpartum women with wrist pain. Seventeen wrist pain patients were recruited and were randomly divided into two groups: experimental group (n=8) and control group (n=9). Participants in both groups received taping therapy for 30 minutes before the intervention. Additionally, subject in the experimental group performed wrist stabilization exercise using theraband for 15 minutes (twice a day, five times a week for four weeks) while the control group conducted range of motion exercise for the same amount of time. VAS was used to assess pain level of wrist. Disability was measured using a DASH. Quality of life were measured by SF-36. The wrist pain in the experimental group improved significantly greater than the control group (p<0.05). Significant improvement in the disability was observed in the experimental group compared to the control group (p<0.05). The SF 36 in the experimental group improved significantly greater than the control group (p<0.05). Our findings indicate that wrist stabilization exercise combined with taping is beneficial and effective to improve wrist health and quality of life in postpartum women with wrist pain.

  • The purpose of this study was to investigate the therapeutic effect of fludrocortisone in patients suffering from cervical spinal cord injury (SCI) with orthostatic hypotension (OH). Twenty-six patients with cervical SCI diagnosed with OH through a head-up tilt test were randomly assigned, and they were given either conservative treatment or additional fludrocortisone treatment. Fludrocortisone was administered for 2 weeks, increasing from 0.1 mg to 0.2 mg week . Blood pressure (BP), heart rate (HR), and blood parameters were measured at the beginning and after 2 weeks. After 2 weeks of treatment, there was a significant increase in the baseline BP of the treatment groups (p<.05). When analyzing the drop ratio, there was a tendency for a lower orthostatic BP drop in the treatment groups. Mild adverse events were reported in 7.69% of the treatment groups. Fludrocortisone exhibited therapeutic effects such as preventing cardiovascular complications and continuing rehabilitation through increased baseline BP and reduced OH, and can therefore be considered as a treatment option for OH in patients with SCI.

  • In this study, we investigated the effects of stretching and movement with mobilization in lunge position on the muscle activity of the lower limb and limited of stability in chronic stroke patients with hemiplegia. Sixteen subjects were randomly selected and classified into the experimental and control groups. The experimental group performed self stretching exercises in the lunge position, and in the control group performed movement with mobilization in the lunge position. The interventions were conducted for 20 min, 5 times a week for 8 weeks. Statistical analyses were performed using repeated ANOVA. The analysis results showed no statistically significant between-group differences with respect to the muscle activity(%MVIC;maximum voluntary isometric contraction) of lower limb and limited of stability(LOS)(p>.05). However, statistically significant within-group differences were observed in the maximum voluntary isometric contraction and limited of stability for both the groups (p<.05). Therefore, self stretching in the lunge position is considered to have positive influences on the muscle strength and balance in stroke patients with hemiplegia.
